Vacuum Tube - 12AT7 / B739, Genalex Gold Lion, Gold Pin
Genalex Gold Lion ECC81/B739 (12AT7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC81/B739 tubes are considered the best 12AT7 types ever made. They are also among the rarest types available. They exhibit a large detailed soundstage that is characterized by an expressive midrange, deep tight bass, and a smooth extended high end. The reissue Genalex Gold Lion ECC81/B739 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

Product Reviews
Pricey yes but a very high quality tube. I used these tubes in my Fender Twin Reverb for the reverb and phase inverter. The reverb is much quieter now hum wise as is the amp. My reverb always had a slight hum. This tube fixed that. A big improvement over the Fender GT's which were Sovteks in my amp. For me they were worth the money.
